Question

04 multiple choice
which cell processes will move solutes with a concentration gradient? (choose all that apply)
diffusion
facilitated diffusion
osmosis
active transport

Explanation:

• Diffusion: Moves solutes from high to low concentration (with gradient).
• Facilitated diffusion: Uses proteins to move solutes down concentration gradient.
• Osmosis: Moves water (solvent) down its concentration gradient (related to solute gradient).
• Active transport: Moves solutes against concentration gradient (requires energy), so not with gradient.

Answer:

A. diffusion, B. facilitated diffusion, C. osmosis
